Hi all. I was diagnosed with GPA in 2017. Initial 6 month treatment of cyclophosphamide and prednisolone. I have had 2 relapses which were treated with courses of rutixumab. I have been on azathioprine now for 15 months and after a phased reduction of preds, I have been steroid free for 5 months.
I have recently started to get a lot of pain in my knee joints and is more painful when I sit for a while then try to walk
GP suspects ostioathritus.
Could any of the meds I have taken caused this or is this just a stroke of bad luck.
